I burned an SVCD and it only plays smoothly if I fast forward the svcd. Is there one thing I am doing wrong that causes this when I burn or when I convert my avi's to MPEG-2?

I used TMPG to convert an avi file and then used VCD Easy to burn it. The sound and video only plays normally if I play the cd in fast forward mode.

I'm sorry if this is a really STUPID question, but I don't know where to find the answer.

Thanks,

Laryssa
